Paper Abstract

In conjunction with conventional techniques intracavity dye laser photoacoustic spectroscopy, an extremely sensitive technique for probing highly forbidden vibrational transitions in the visible spectrum (10,000-25,000 cm-1), has provided new insights into the nature and dynamics of the C-H stretch vibrational manifold of gaseous cyclopropane. Observations of strong coupling of the manifold to low frequency CH2 deformation modes and linebroadening of high energy vibrational states are discussed in terms of intramolecular vibrational energy relaxation processes and related to infrared multiphoton chemistry of cyclopropane.
